SecMGW — An Open-Source Enterprise Gateway for Secure E-Mail
Tobias Straub, Matthias Fleck, Ralf Grewe, Oliver Lenze · 2004
Securing e-mail with cryptography and PKI is an effective countermeasure against common threats like SPAM, malware, or industrial espionage. Compared to the troublesome handling of PKI-enabled applications by end-users, the idea of a centralized gateway managing all cryptographic tasks seems very attractive. However, such a gateway represents a single point of attack as it stores a lot of keys. We show how to address this issue by means of threshold cryptography and describe the SecMGW concept which easily integrates in existing environments. SecMGW was implemented solely using open-source products making it a cost-effective solution, well-suited for small and medium enterprises.
